Hi, I need to read amplitude values from my Raven recordings, i.e. like from an oscilloscope. Is it correct to do as follows:
1. I recorded with gain setting 0.5V
2. selecting Calibration I chose Electric, full scale, 0.5V
Then the Y scale showed +- 250, which I assume is mV.
Finally I read max plus and minus amplitude for my sounds, in mV, sum them to get mVp-p, and use that for my SPL calculations, where I take into account hydrophone sensitivity and preamp gain.
Correct?
thanks,
mats

Hi Mats,

That looks reasonable. Regarding the Y scale, once you have set up calibration the units should be displayed in the lower left corner of the waveform view as "mV", "V", or whatever is appropriate.
